Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593902, here are decompositions:

139 + 31593763 = 31593902
181 + 31593721 = 31593902
199 + 31593703 = 31593902
271 + 31593631 = 31593902
313 + 31593589 = 31593902
331 + 31593571 = 31593902
349 + 31593553 = 31593902
709 + 31593193 = 31593902

Showing the first eight; more decompositions exist.
